Does CBD Oil Really Work?

It's been nearly a decade since pilot programs reintroduced hemp cultivation to American soil. Although numerous skeptics assumed the "CBD craze" would diminish over time, consumer demand continues to rise. But despite the many positive reviews and user testimonials, many people who are curious about CBD still aren't convinced the cannabinoid really works. Sound familiar? 

Whether your investigations have you leaning in favor of purchasing CBD oil or you're just beginning your search, it's important to have all the facts. In this CBD guide, you'll have a chance to compare the observations reported by CBD users to the results of clinical studies. But first, we'll explore what CBD is, how it works, and why you may want to consider indulging your curiosity.  

CBD and the Human Body: What It Is & How It Works 

CBD (cannabidiol) is a plant element, a cannabinoid that functions a lot like two substances produced as needed in your body: anandamide and 2- Arachidonoylglycerol (2-AG).10 It's the most abundant of the many cannabinoids in hemp flower. Marijuana plants also produce CBD but in smaller amounts. Once the cannabinoid-rich oil is extracted and distilled, it's used as an ingredient in a vast assortment of products, CBD oil tinctures, topicals, softgels, gummies, and more. 

Once the CBD from a hemp-derived product is absorbed into your bloodstream, the cannabinoid interacts with more than 65 molecular targets, including the receptors of your serotonin, dopamine, and GABA systems.3 However, researchers tend to credit CBD's most impactful contributions to its influence on the endocannabinoid system (ECS) receptors.7 Based on lab results and a rapidly growing number of clinical trials, cannabis researchers believe CBD's impact on ECS receptors helps support the processes of homeostasis.12 

Evaluating the Claims: Comparing Anecdotal Evidence to the Results of Clinical Studies    

Despite multiple cautionary reports of product mislabeling, numerous companies caught making unsubstantiated claims, and people initially believing hemp and marijuana were one and the same, our industry thrived. We owe those early successes, at least in part, to consumer interest in the cannabinoid's impact on the body, a steadily increasing number of clinical trials, and the testimony of CBD users claiming considerable benefits for an impressive number of health and wellness concerns. 

Take the responses to our 2019 CBDistillery® customer survey, for example. Based on the feedback of 1,900 respondents, most CBD users reported positive results for relaxation, better sleep (89%), and pain, stiffness, and inflammation after physical activity (84%). An impressive 89% claimed CBD helped calm their minds, and 88% reported a positive impact for mild or temporary anxiety. Researchers have documented effects similar to the responses provided by our survey respondents, observations you'll find in the following examples. 

Discomfort After Physical Activity  

In a review of the available data published in 2021, the author details CBD's influence on several homeostatic regulators. The report included "promising "evidence supporting the cannabinoid's use for "sport-related fatigue," recovery efficiency, and other factors relevant to repetitive motion.11 In a similar report published a year earlier in Sports Medicine – Open, researchers credited CBD for multiple biochemical and physiological effects identified as potentially beneficial for athletic recovery.

Relaxation & Sleep Support  

In laboratory tests and clinical trials investigating CBD's possible contributions for sleep duration and quality, researchers have documented effects quite similar to the responses of our survey participants. At the conclusion of a two-year study, for example, researchers reported "statistically and clinically significant" benefits related to sleep quality using CBD-dominant cannabis.14 In a similar report published several years later, investigators specifically noted CBD's positive impact on sleep duration.

Mild or Temporary Anxiety  

The clinical evidence supporting CBD user claims related to mild or temporary anxiety is also quite compelling, particularly for anyone kept awake by the impact of stress. During a 2019 study involving 103 participants, researchers credited CBD's positive impact on sleep scores to its "calming" effect.13 Study participants given CBD before a simulated public speaking event reported less physical discomfort, less stress-induced cognitive impairment, and lower anxiety levels than those receiving a placebo.

Further Considerations: Consumer Safety and Product Legality  

Despite numerous websites claiming CBD is legal nationwide, our federal government left the determination of legality to the states. Although most allow unrestricted use of hemp-derived products with THC concentrations below 0.3% (by dry weight), some states only allow the consumption (or topical application) of products with non-detectable THC levels. There are several that ban cannabis use entirely. Since state laws vary, we highly recommend reviewing the legislation in your area before committing to a purchase. 

As far as safety goes, CBD oil is generally well-tolerated and safe for most people.According to a 2020 report published by the World Health Organization, the agency found "no evidence of public health-related problems"15, and researchers investigating CBD's possible impact on liver function found no evidence of impairment in healthy adults.5 However, that in no way means CBD is right for everyone. 

Some CBD users experience dry mouth, fatigue, nausea, or changes in appetite.2 CBD is also known to interact with several prescription and over-the-counter medications, and cannabis products of any kind are not appropriate for people diagnosed with certain medical conditions. We strongly suggest consulting your healthcare provider before adding any hemp-derived products to your daily routine if you have questions or concerns. 

Guidelines for Safe CBD Consumption  

The FDA has determined their framework is insufficient for regulating CBD products. As it stands, there are multiple loopholes, little manufacturer oversight6, and quality assurance testing is not universally required. The agency is currently working with Congress to develop and implement a better approach. Until that happens, it's up to CBD manufacturers to ensure their products are accurately labeled and safe for consumption. As within every industry, some companies take their responsibilities more seriously than others. 

You can protect yourself from purchasing products of questionable quality by sticking with brands backing their claims of purity and potency with a certificate of analysis (COA). That document is the best way to confirm the products you select are as potent as the manufacturer claims and third-party batch tested for heavy metals, pesticides, extraction residue, and microbial contamination. If you don't have access, shop elsewhere. Of the 75% of companies claiming their CBD products are third-party tested, only about 13% submit samples for at least 90% of their products.4 

The Final Verdict: You Won't Know If CBD Really Works Until You Try a High-Quality Product 

A quick internet search will direct you to a considerable number of user testimonials, lab reports, and clinical studies supporting the health and wellness potential of hemp-derived CBD products. But the research is still ongoing, and no two CBD users are exactly the same. The only way to know how your system will respond is to purchase a quality-assured product and try it. 

Before you do, you'll want to keep in mind that the amount of CBD that works for one person can be quite different than the serving size ideal for another. Although using more CBD than you need is not harmful, there's also no additional benefit. Instead of starting with the serving size suggestions printed on package labels, consider starting with a smaller amount. Then, increase your serving sizes gradually (if needed) over time. But you may need to be patient. 

Despite numerous reports from CBD users claiming impressive results within hours of their first serving, it could take time for your system to adapt and respond, anywhere from multiple days to several months. While you're waiting, you may find it at least somewhat reassuring to know that most of our survey respondents reported achieving their best results within 7-14 days of consistent use.
